Valvetronic servo failure

Post by BreadBin » Mon Sep 09, 2019 10:28 am

My E82 has finally succumbed to the inevitable (the signs have been there for a while) Valvetronic servo failure. It now won't start.
Has anyone had any joy with getting this repaired independently as I don't want to get shafted by BMW!

No-one else has had to get their Valvetronic servo replaced?

Thanks, I was actually looking for garage recommendations as it's not a job I can do myself.

Be useful to know what area you are in.

Apologies - I'm in the west, near Shaftesbury.

My N55 335i Had the valvetronic servo replaced before I bought it.

Was around £1500 from a main dealer. :shock:

How can they possibly justify that cost?? The part is only around £300 itself and it's no harder to get to than the spark plugs!

These guys have it exposed in less than 5 minutes! :https://www.youtube.com/watch?v=lGS9dptlN3Q

They will have replaced the eccentric shaft too, that's the recommendation.

That's the rip off BMW postion you mean. Unless the teeth have stripped on the shaft there is no way it's going to have enough wear on it to require replacing. At least if you're ever going to replace it due to wear then you'd need to be looking at replacing the crank and camshafts too as they are all under 1000x more load and wear than the eccentric shaft will be.

Unless i'm totally misunderstanding what the shaft does, it's under practically no load (in engine terms) so why would it wear sufficiently to require replacement on anything but extremely high mileage engines?

What signs have been there for a while I’ve never heard of this failure?

This sound, for a few months. It hasn't done it every time.

The one on mine went at less than 30k with full history. I have no idea why BMW didn't cover the cost as a goodwill gesture.
